Made from 1018 carbon steel.

Store the block in the included ABS plastic case when not in use.

Keep all step surfaces clean, dry, and free from corrosion, dents, burrs, and heavy scratches.

Wipe off ultrasonic couplant after each use to prevent residue buildup or surface oxidation.

Apply light corrosion protection when storing for extended periods, especially in humid or marine environments.

Avoid dropping, striking, or machining the block, as surface damage can affect calibration reliability.

Handle with clean hands or gloves and wipe after use to reduce fingerprints and rust risk.

Verify certification details and dimensional tolerances before using in controlled inspection procedures.
